I know Ponca City and Enid had nonstops to/from Denver by Air Midwest or Big Sky Airlines (one of those "small-town" EAS carriers) with Swearingen III Metroliner turboprops, but that was way back in the day, mid-late 90s if memory serves well. After that, it's been only three airports in the state with scheduled commercial service. Nice to see Stillwater join that list.

Hope this one lasts for a while, it will be great for the international student population there as well, which I'm sure has grown quite a bit over the years.
